VALVE OILING AND GAS DILUTING DEVICE Filed May 12, 1951' Patented Feb. 14, 1933 -umrsn ESTATES PATENT OFF ICE HALFORD; OF SACRAMENTO, CALIFORNIA VALVE OILINGAND GASDILUTING DEVICE Application filed May 112,

intake-gases through the intake manifold and controlled by the throttle.

The main object of the invention is to provide means for supplying additional valve oil tothe valves of an internal combustion 0 motor when the motor is idling,#at which time the valves are usually ins'ufiiciently oiled, a certain speed. being required for proper distribution of the usual oil supplied tothe motor.

Another object of the invention is to provide means for partially cutting off the auxiliary supply of oil when the motor is speeded up andprovide additional air and oil, at medium, and moistened air only at high speeds, whereby efficiency is established in the oiling of the-valvesat low speeds without diluting thegas, a partial dilution of the gaseswith air at mediumspeeds, and a'further dilution with moistened air at high speeds, thus increasing thelife, power and economy of the engine.

A still further object of the invention is to control the oiling and gas dilution and moist ening coincident :with operation of the throttle, and governe'dby the speed of the engine, the controlling means being operated coinci'dently' by the throttle: and intake suction.

Other objects and advantagesof theinvention will become apparent as the following 'descriptionis read on'the drawingforming a part of this specification.

The invention consists of a plunger operated valve adapted to successively 'open threedifferent-ports in a housing "which is cylindrical in format one end and'conical in form at the opposite end and provided with apipethreaded portion at the apex, which is adaptedto be secured ina pipe tap in the intakemanifold orv interposed Ffiller between the intake manifold and carburetor of an internal combustion engine.

. The invention isadequat'ely illustrated in the accompanying drawing in which:

ternal combustion enginewith my invention appliedthereto; a

Fig. 2 is a vertical section through the oiler;

Fig. 3 is an internal view of the oiler with the conical portion removed; b Fig. 4 is a plan viewof the mounting memer.

Similar reference characters 'identify'similar parts throughout the several views.

The invention consists of a head 10 of cylindrical form, having a reduced portion 11 provided, with an externalthre'a'd as indicated,fthe head being recessed-as at 13. y A transverse aperture'is provided to .slidably receive the plunger 14 which is cylindrical in form. A plurality of different diameter apertures 15,116 and. 17 extend through the head; the aperture 15 terminating in .a pipe tap 1'8for reception of an oil pipe nipple.

"The body 19 consists of a cylindrical portion 20, internally threaded to cooperate with the-"threaded portion-of head 10; and continuing into the conical-portion 21, the apex conitinuing ,lIltO a hex1portion22 and apipe ithreaded portion-'23 adapted to cooperate with a pipe-tap provided in the intake manifold or in the. mounting member Fig/1.

The valve plunger 14 is of cylindrical form andjhasan enlarged end 24 which is providedwith couplingmeans to cooperate with the engine throttle lever, the opposite :end having a nut 25 cooperating with thethreaded end; and adapted tocooperate with a compression spring26. The plunger is restricted atonepoint shown at 27 A groove 28 in the plungenprovides a restricted fiowof'oil to theaperture 16.

Aflapvalve is provided to closethe apertures '16 and 17 during periods of heavy pulling or quick starting, when the engine speed is low and throttle open, at. which time'the flap valve closes,-and which consists of a plate 29' slidably mounted on a pin '30 and urged to closed position by a spring 31 and rwhich is'openedthrough the vacuum'created within the intake manifold.

The mounting. member consists'of' a; plate the-carburetor andintake-manifold bores, and

V .25 through the water. i

having slots 34 and 35 whereby the member may be installed between the intake manifold and carburetor merely by loosening the bolts and sliding the member in position.

A tapped hole 36 is provided to receive the end 23 of the oiler, or a street L may be interposed. A plurality of apertures 37 communicate between the tapped hole 36 and bore 33.

The invention is installed by securing the oiler in the aperture 86 of mounting member 32, placing member 32 between the intake manifold flange 38 and carburetor flange 39, drawing up the flange bolts, connecting the end 24 of plunger 1& to the throttle lever 40 and connecting an oil pipe 41 between the tapped hole 18 and a supply ofoilin a tank 42. A tube connection is preferably made between the port 17 andan air moistening device'not shown, and which, may consist of a connection fto the upper part of the radiator, as to the topof a closed tank containing water and having an air inlet tube extending down into the water whereby air isdrawn The operation of the device is as follows.

When the engine is idling, the restriction on plunger l l lines up with aperture 15 per mitting oil to be drawn into the intake manifold, thus oiling the valves and preventing air dilution. 4 f r A As the engine is partly speeded up, plunger 14 isd rawn down closing port 15 and opening port 16 allowing additional air to be drawn into the motor, and coincidently therewith, oil through the groove :28. Further retraction of the plunger l icloses port 16 and opens port 17 admitting water moistened air to the intake manifold at thehigher speeds. With the throttle open and engine turning over slowly, the valve 29 closes ports 16 and 17 Economy in gasoline consumption and efliciency in oiling are thus provided, the life of the valves is increased, and the power is increased by admission of moisture at high speed, the excessive heat being converted into steam and thus reducing the temperature without sacrificing pressure.

Having described an operative method of constructing and using thedevice, it will be understood that variations in construction and arrangement which are consistent with the appended claims may be resorted to with out detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof.
